PIECEWISE TABLE BLOCK

9-8

05

Can Be Inverse Piecewise (CANBEIPW) .........................................................................C – R
If the Y values are in ascending order and there are no duplicates, the table is marked as
usable for inverse piecewise linearization.

06

Number of Points (NUMPTS) ...........................................................................................C – R
The number of point pairs configured.

101, 201

X1, Y1 ................................................................................................................................ CWR

160, 260

X60, Y60 ............................................................................................................................. CWR

1 to 60 Enter the floating point value for at least 2 points (if linearization is

required) and as many as 60 points. For each point, both the X and
Y values must be entered.

Typical Block Connections for Piecewise Table Block

Typical softwiring block structures used on softwiring diagrams are shown in Figure 9-4. The
analog input signal is from a non-Linear device. The TABLE field of the linearization block is
set at PW1. The piecewise block provides the data used to linearize the continuous signal
from the non-linear device. If two (or more) non-linear devices are of the same type and have
same output characteristics, then the same piecewise block can be used to linearize both
input signals. The PW2 connections contain recipe data for a Tune List block. The list is made
available to a MOD 30ML Display block as shown.
